SPECIFICATION forming part of Letters Patent No. 426,792, dated April29, 1890.

Application filed June 28,1889. Serial No. 315,910. (No model.)

To all whom it may concern.-

Be it known that I, JAMES H. FOOTE, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in VVindow-Sashes; andI do declare the following to be a full, clear, and exact description ofthe invention, reference being had to th'e accompanying drawings, whichform a part of this specification.

This invention relates to those windowsashes which are capable of beingraised and lowered within a frame or casing and of being turned onpivots, so as tobe either horizontal or inclined at any position thatwill be most convenient or effective for cleaning or ventilation; andthe first part of my improvements comprises a novel combination ofdevices for operating a hollow guide that traverses a vertical groove ofthe frame. Vhen these devices are so operated as to advance the guidelaterally within the groove, the sash can then be raised and lowered inunison with said guide; butwhen the latter is retracted within saidgroove the sash is free to be turned on its pivots, as hereinafter morefully described.

The second part of my improvements comprises a novel combination ofdevices for locking the pivots, in order that the sash may be retainedin an inclined or horizontal position, as hereinafter morefullydescribed.

My improvements further comprise certain details in the construction ofthe pivot mechanism, the particulars of which will be hereinafter morefully described, and set forth in the claims.

In the annexed drawings, Figure lis a sectionized elevation of one of mypivotbearings for a sliding and swinging window-sash, said sash beingarranged to be raised and lowered with the guide. Fig. 2 is a horizontalsection of said bearing, taken at the line X X. Fig. 3 is anothersectionized elevation, but showing the sash supported by the pivot, soas to be turned thereon. Fig. 4 is a horizontal section thereof, takenat the line YY. Fig. 5 is a front elevation of the face-plate of thecase that contains the pivot mechanism. Fig. G is an enlarged verticalsection of said case, taken at the line Z Z. Fig. 7 is an enlarged planof a portion of the guide and the edge plate of the case. Fig. 8 is anenlarged horizontal section of the devices that operate the cam-shaft ofsaid case. Fig. 9 is a detail view of a portion of said shaft.

A represents a portion of a box Window frame or casing, and d is avertical groove therein, which groove is traversed by a hollowthree-sided guide B, that is preferably made of sheet metal, and isusually as long as the sash to which it is applied. This hollow guidehas near its mid-length a vertical slot b, traversed by a bolt C, havinga notch c at one end and a cylindrical shank c near its opposite end,said bolt being adapted to slide within a vertical slot (Z of a barrelD, Whose periphery is grooved or fluted longitudinally at d.

d is a head on one end of this barrel, which latter is adapted to slidefreely within a cylindrical'neck or socket c of the edge plateE of acase F, within which case the principal operative parts are housed, inthe manner shown. G is a vertical stop secured within this case, as seenin Fig..6, said stop being furnished with a circular opening g, to admitthe boltshank c', and a vertical slot g', through which said boltpasses, the inner end of said bolt having a pair of collars or nuts HH', between which is inserted the free and forked end of a spring I, thefixed extremity of the latter being fastened to a rock-shaft J, carryinga pair of cams K K. These cams are adapted to bear against the lowerends of bent levers L L', pivoted at Z Z to the case and its cap andnormallyheld in contactwith thebarrel-head d. Rock-shaft .I is suitablyjournaledwithin the case and cap and has at one end a socket j, (seen inFig. 3 and indicated by dotted lines in Fig. 9,) which socket receives asquare or other non-circular arbor m at the inner end of a spindle M,the exposed end of the latter being provided with any approved form ofhandle or other convenient turning device m. Spindle M is groovedlongitudinally at m to admit a plate-spring N, Whose free end carries apawl n, adapted to engage with a segmental ratchet O, properly securedoutside the case, the screw or pin n', that fastens said spring, servingas a stop to prevent said spindle being drawn too far forward. Thespindle-handle m may turn within a pit p, cast in the face-plate Pof thecase,

IOO

as seen in Fig. 5; but I prefer the arrangement represented in Fig. 8,in which illustration the spindle M is shown as passing through acentral circular hole q of a dished plate Q, having an annular flangeq', seated against a bearing p of the face-plate and held in place by ascrew-threaded ring Q. p are screws that secure this plate to thewindow-sash R, the edge of the latter having a vert-ical groove r,suitably mortised to admit the case F and its cap S, which cap ispierced, as at s in Fig. 9, to receive the end of rock-shaft J.

Face-plate P is slotted horizontally at j? for the passage of therounded portion t of a catch T, suitably pivoted to the rear of saidplate, as seen in Fig. 2, the free end of this swinging catch beingadapted to enter either one of the grooves d. of barrelD. The pivot ofthis catch has a pair of fiat facets, against either one of which thespring t bears, and thus holds said catch either in geai.` with thebarrel or out of gear therewith.

t is a small projection wherewi th the catch T is swung either to theright or left, as occasion requires.

U U are duplex eccentricsor cams united by a pair of rounds or bars uu',one of which, as u', is grasped by the notch c of bolt C, while theother bar u has a hook V attached to it. i* is a sashcord attached tothis hook, which cord or chain is passed over apulleyin the frame, andis then carried down within a suitable box or casing and furnished witha customary weight capable of balancing the sash in the usual manner. XVis ascrew that unites the cap S to the case F.

lVhen the various parts of my sash are in their normal positions, theupward pull of saslreord o causes the freely-suspended cams U U to bearagainst the guide B with sufficient pressure to force it into the groover until it comes in contact with the edge plate Eef case F, as moreclearly seen in Fig. Land the hook c, being engaged over the bar u',couples the sash R to said cams and through them to the sash-cord, thespring I preventing any accidental detachment of said hook. It isevident the sash is now suspended from the cord r, and as the hollowguide B is inserted in part within the groove a of the frame and in partwithin the groove i' of the sashit is apparent said sash is nowincapable of being swung or turned in `either direction, but is free tobe raised and lowered in the usual manner, the guide B confining saidsash to a strict vertical path; but when it is desired to swing or turnthe sash the small projection t is pushed to the right, so as to throwthe catch Tout of gear with the grooved barrel D d', and the handle m isthen turned in the proper direction to cause the cams K K to act againstthe levers L L', and thereby shift said barrel longitudinally until itshead d strikes against the end of neck e, as seen in Fig. 3. Thisadvance movement of the barlll rel forces the guide l entirely'out ofthe sash groove r and drives said guide into the framegroove u, as seenin Figs. 3 and 4. Consequently the sash is now supported wholly upon thebarrel D, which serves as a pivot or bearing around which the collar cturns with perfect freedom, and when the sash has been turned in thismanner until the desired angle is obtained the catch T is brought intoservice and by engaging withanother one of the barrel-grooves serves tolock the sash in position. Although the sash is now inclined orperfectly horizontal, if desired, it can be raised or lowered as before,but cannot aceidentally turn upon its pivots. To restore the sash to avertical position, the catch T must first be intentionally disengagedfrom the grooved barrel D cl', as previously described, and then byretracting said barrel the guide B advances into the groove r and allthe parts are restored to their normal places. This lateral sliding ofthe guide into the sash* groove is readily effected on account of thepressure exerted against said guide by the sash-weight pulling on thefreelysuspended eccentrics U U', which have no connection with saidguide, but simply bear against it. Previous to advancing the guide thespindle M is shifted forward as far as the pin 'a' will permit, whichact disengagcs the pawl n from ratchet O and allows the rock-shaft .l tobe turned back until the cams K K assume the position seen in Fig. l.Spindle M is then forcedmback, so as to enable the pawl n to re engagewith the ratchet O, when the sash is again operated, as previouslydescribed. It is preferred to eorrugate the face of the edge plate E, asseen in Fig. 7, and also to corrugate the guide, thereby stiifening thelatter and causing it to havea spring action within the mframe-guide.The dotted lines in this illustration show that the cams U U can bearagainst the concave portions of the corrugated guide.

In Figs. 2 and 4i considerable space has been IOO IIO

left between the bolt C and cams U U and between the latter and thesides of guide B, so as to prevent these parts being confused in thedrawings; but said parts should be fit ted up quite snugly to eachother, as indi cated by dotted lines in Fig. '7, so as to pre vent anymaterial playA I claim as my invention-e l.
